Add two durations

Hi everybody,

I'm using foo_skip to skip the beginning of some of my tracks.
I'd like to use a special column to display the accurate played length of such tracks.
For example a 4 minutes track where I will skip the first 15 seconds will have these fields :
%length% = 4:00
%skip% = -00:15

How could I add these two durations, to ultimately display the accurate played length which is 3:45 ?
$add(%length%;%skip%) doesn't seem to work here.

Thank you. :)

It's quite complex. Here's a script that handles calculating final length only with -[hh:][mm:]ss skip string syntax:
Code: [Select]
$if(%skip%,
$if($strcmp($left(%skip%,1),-),

$puts(st,$pad_right($replace(%skip%,-,,:,),6,0))
$puts(ssecs,$right($get(st),2))
$puts(smins,$substr($get(st),3,4))
$puts(shrs,$substr($get(st),1,2))
$puts(slen,$add($mul($add($mul($get(shrs),60),$get(smins)),60),$get(ssecs)))

$ifgreater($get(slen),%_length_seconds%,%length%,

$puts(plen,$sub(%_length_seconds%,$get(slen)))

$puts(psecs,$mod($get(plen),60))
$puts(pmins,$mod($div($get(plen),60),60))
$puts(phrs,$div($get(plen),3600))

$ifgreater($get(phrs),0,$get(phrs):$num($get(pmins),2),$get(pmins)):$ifgreater($get(psecs),0,$num($get(psecs),2),)))

,%length%)

Thanks Case. It is quite complex indeed. :)
It doesn't work in my case, probably because I'm using %skip% down to the 10th or 100th of second, so my skip string syntax is either -mm:ss, or -mm:ss.0, or -mm:ss.00 (no hours, never)
I know, that's complicated. Too bad foobar doesn't have an integrated calculator for this kind of thing. ;)

I've created something that works. It's not a pretty code, but it works with my 3 syntaxes :

Code: [Select]
$if(%skip%,$puts(a,$sub(%length_seconds%,$add($mul($substr(%skip%,2,3),60),$substr(%skip%,5,6))))$div($get(a),60)':'$pad($sub($sub($get(a),$mul($div($get(a),60),60)),$if($or($strstr(%skip%,'.6'),$strstr(%skip%,'.7'),$strstr(%skip%,'.8'),$strstr(%skip%,'.9')),1,0)),2,0),%length%)
